How to beat 3-4-3?

[bellbtwouty]

today I have a match with him again. last time I lost a game 2-3, he used 3-4-3, I used 3-4-3

now he is still using 3-4-3 and he has not changed his players
his team:

(13)ST--(12)ST--(13)ST
------------------------
(16)ML-(12)MC----------12)MC-(14)MR
-----------------------
(19)DC--(13)DC--(12)DC
(13)GK

I have players are good quality just DC(19), AMLAMC(24) other just 11-14 quality

Finally I won 1-2 and I used 4-5-1

[Ray Tarabass]

I used Hexagon, with counter on and won 3-0.
Played at home, and my opponent is a little bit stronger than me.

[Adam Marszał]

I add my situation also to this question.
Today I've played at home the first cup game.
Oponent played 3N-4-3.
I played 4-3N-2W-1.
The result was 0-0 so tomorrow I have to score and draw or win.
In my team I don't have MR and I have very weak AMC and only 2 striker (one of them is poor)...

This is my second season so i'm still building the team. Maybe I will buy anyone tomorrow but I cannot be sure about it on transfer market...

Can someone suggest something?
